Sigma 24mm f2 DG DN Contemporary - L Mount - 1060309

The SIGMA I series features full-frame-compatible lenses that offer mirrorless users a new and better alternative, both in the experience of shooting with the lens and in the impressive results it is able to achieve.

One of the key advantages of mirrorless cameras is their smaller form-factor, and this new 90mm optic is designed to be perfectly matched to these more compact systems without sacrificing performance. This combination of superb optical quality with exceptional portability, not previously possible with DSLR systems, will bring new opportunities to this and future generations of photographers.

Simultaneously, SIGMA is aware that, in this day and age when we have such huge diversity when it comes to what we use to photograph, as represented by smartphones, people look for something more than a mere act of "taking pictures" when they choose to own a camera and lenses.

SIGMA's excellence in development and processing technologies has been built up since it was founded in 1961, and has become further sophisticated with the introduction of the SIGMA Global Vision in 2012. With this as a base SIGMA has given careful thought to how photographers use and enjoy their lenses, including optical design, advanced functionality, build quality and the experience of picking up and using the lens, and with all of this carefully considered the I series was born.

New standards of optical performance for the Contemporary line

The SIGMA 90mm F2.8 DG DN | Contemporary boasts exceptional optical performance with a ultra-high resolving power to match the latest high-resolution mirrorless cameras.

The lens is built using the very latest optical technology, and includes five SLD glass elements. This helps to reduce axial chromatic aberration that cannot be corrected in-camera, allowing the lens to achieve high resolution and clear image quality with no color bleeding. A high-precision glass molded aspherical lens provides both high resolution and beautiful bokeh. Photographers can enjoy shooting with soft, large bokeh without coloration and this is something that only a full-frame lens is able to deliver.

The lens also utilizes the camera’s optical correction functionality, which is an advantage of mirrorless systems, SIGMA's optical designers were therefore able to concentrate on correcting aberrations that can only be corrected by the optical design, thereby improving rendering performance and reducing the size and weight of the lens.

With a minimum focusing distance of 50cm and a maximum magnification ratio of 1:5, close-up macro-style photography is possible. The lens highlights the subject, allowing photographers to focus in on fine details or create more abstract compositions.

The AF drive system incorporates a quiet, high-speed stepping motor, making it suitable for still images as well as video recording.

Exceptional I series build quality with a compact form-factor

All I series lenses have an all-metal construction. The precision-cut aluminum parts not only give the barrel a sleek, stylish finish, but provide superb durability that improves the quality of the entire product. Metal materials are also used in internal structures that slide with the operation ring for added robustness. These high-precision components crafted with SIGMA’s cutting-edge metalworking technology are also used in SIGMA’s cine lens line-up for professional cinematographers and provide a tactile, ergonomic feel that make the lens a pleasure to use.

The 90mm F2.8 DG DN | Contemporary shares the same φ64mm maximum diameter and 55mm filter size as the 24mm F3.5 DG DN | Contemporary and the 45mm F2.8 DG DN | Contemporary, making them a natural trio, especially for filmmakers who use filters more regularly. With a combined weight of only 735grams / 25.9oz.^※, these three lenses (wide-angle, standard, mid-telephoto) can be used in tandem as part of a high-spec and compact camera system that covers a wide range of shooting situations.

Maintenance Tips

• Clean Glass Safely: Gently use a blower to remove dust and then a microfiber cloth with lens‑safe solution to wipe front/rear elements; avoid pressing too hard to protect the multi‑element, multi‑coated optics. (Standard lens care)
• Use Caps & Hood: Always attach the supplied front/rear lens caps and the petal‑type hood to prevent scratches, reduce flare, and keep dust and moisture off the glass.
• Avoid Fingerprints on Glass: Handle the lens by the barrel and mount, not the glass; fingerprints can attract dust and oils that impair contrast and require more frequent cleaning. (General photography best practice)
• Protect in Storage: Store in a dry, padded camera bag with silica gel packs to minimize humidity and prevent fungus growth inside the lens elements. (Standard lens care)
• Dust/Splash Resistance: Take advantage of the L‑Mount’s rubber sealing at the lens mount for moderate dust/splash conditions; still avoid direct moisture exposure.
• Update Firmware (if applicable): Check for firmware updates via your L‑Mount camera (attach lens and follow Sigma update procedures) to improve autofocus and performance stability.
• Mount/Unmount Carefully: Align mount indexes carefully when attaching/removing to protect the durable brass bayonet and electrical contacts.
